Scope
Main technical content: This standard specifies the terms, definitions, symbols and codes, product types and characteristics, basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage, and quality commitments of multi-functional conversion switches (hereinafter referred to as "conversion switches"). This standard applies to circuits with an AC frequency of 50 Hz or 60 Hz, a rated voltage of not more than 400 V, and a DC voltage of not more than 220 V, where the conventional heating current (Ith) does not exceed 10 A. It is suitable for use in electrical control circuits (controlling electromagnetic coils) and direct-acting switches for converting the starting of main switches and energy storage mechanisms of electric motors.
